In Space, You're Never Alone

Trenton Fort is an average twelve year old boy. He's homeschooled, yeah, and living with his mother in the middle of the Texas Panhandle, but other than that and the fact that his dad is a wanted intergalactic criminal, he's pretty normal (for a kid whose mother is taken in for questioning by a bunch of brutal psychopathic alien policemen).
When that happens, he and his estranged father must get over their differences to rescue her before it's too late.
